  • the pairs of tracks of the first and of the second type are arranged so as to alternate in the circumferential direction.
  • the number of the pairs of tracks is an even number, more particularly amounts to 6, 8 or 10.
  • US 2007/0111806 A1 corresponding to WO 2006/048032 A1 , proposes a counter track joint of said type.
  • the ball tracks - which in the central joint plane of an aligned joint, open towards the attaching end - at the attaching end, comprise a first arched portion with a small radius; in the region of the central joint plane, they comprise a second arched portion with a greater radius; and at the aperture end, they comprise a third arched portion which, relative to the second arched portion, comprises an opposed direction of curvature.
  • the ball tracks which, in the central joint plane of the aligned joint, widen towards the aperture end, according to a first embodiment, comprise the same radius along the entire length of the ball tracks; or according to a second embodiment, they comprise an arched portion which, with a uniform radius, extends from the attaching end beyond the central joint plane and which, at the aperture end, is adjoined by a counter radius or, according to a third embodiment, they comprise an arched portion with, with the same radius, extends from the attaching end beyond the central joint plane and which, at the aperture end, is adjoined by a tangent.
  • the ball tracks which, in an aligned joint in the central joint plane, widen from the attaching end towards the aperture end, comprise a circular arch with a uniform radius from the attaching end to the central joint plane, which circular arch, at the aperture end, is adjoined by a tangent.
  • US 2010/0323802 A1 proposes a further counter track joint.
  • the ball tracks opening in an aligned joint in the central joint plane from the aperture end to the attaching end extend in an S-shaped way.
  • the ball tracks which widen in an aligned joint in the central joint plane from the attaching end to the aperture end extend in an S-shaped way and are composed of a rear arched portion with a large radius; in the region of the central joint plane, they comprise a central arched portion with a smaller radius as well as an arched portion at the aperture end, which arched portion, relative to the central arched portion, extends in the opposed direction of curvature.
  • the ball cage comprises an outer spherical face with an internally spherical centre, wherein the externally spherical centre and the internally spherical centre are arranged so as to be offset relative to one another.

  • the wrap angles of the ball tracks around the balls in the inner joint part and in the outer joint part are more aligned to one another and thereby enhanced.
  • the objective is achieved by providing a constant velocity joint in the form of a counter track joint comprising
  • the advantage consists in that because the first track centre line extends towards the attaching end inside the reference radius, there are achieved improved cage control conditions at large articulation angles. This is due to the fact that, in the rear portion, the introduction of force from the first pairs of tracks to the balls and from the latter to the ball cage is improved. As a result, the forces acting on the ball cage are particularly well balanced. Overall, there is thus provided a joint by means of which it is possible to achieve particularly large articulation angles, and because of the improved cage control conditions, there is little noise, vibration and harshness (NVH).
  • the rear track portion of the ball tracks which, when the joint is in an aligned condition, open towards the aperture end (track centre line A) are curved radially inside towards the attaching end.

  • the first track centre line A Up to said angle, which is enclosed between the joint centre plane EM and a line through the joint centre M and the centre of the ball, the first track centre line A has a relatively small curvature in its central portion.
  • the curvature is stronger, compared with the curvature of the central portion.
  • the mentioned angles between the centre of the ball and the joint centre plane, starting from which angles the track centre line A runs radially inside the reference radius, are preferred values. It is understood that the track centre line A can also run radially within the reference radius already in smaller angle regions with respect to the joint centre plane EM, such as starting from an angle of 3° for example.

  • the constant velocity joint is operated in service life operation. This means that, when the joint is operated within said angle range, the design service life of the joint is reached under changing load conditions, without the joint suffering any damage. Therefore, said angle range on both sides of the joint central plane can also be referred to as service life angle.

  • the central curved portion A1 of the first track centre line A can be formed by a curve of a higher order, e.g. by an ellipse, a spiral or a hyperbola, instead of being formed by a circular arch with a uniform radius.
  • the curvature of the central curved portion A1 would be increased towards the attaching end continuously, so that the first track centre line A in said portion moves away radially inwardly from the reference radius RRA.
